Title: Nonwoven, melt blown fluid filtration media with integral co-located support and filtration fibers, filter cartridges employing, and methods and apparatus of making, the same
Inventor: SCHMITT ROBERT JR
IPC: D04H3/03
Filed: 1996-04-10
Abstract: Filtration medium is formed of a mass of non-woven melt blown support and filtration fibers which are integrally co-located with one another. The support fibers (32) have, on average, relatively larger diameters as compared to the filtration fibers (30) which are integrally co-located therewith. Preferably the filtration medium is disposed within at least one annular zone of a filtration element, for example, a disposable cylindrical filter cartridge having an axially elongated central hollow passageway (12) which is surrounded by the filtration media. A depth filter cartridge in accordance with the present invention may thus be formed having one or more additional zones (Z1, Z2, Z3) (which additional filtration zones may or may not respectively be provided with integrally co-located support fibers) in annular relationship to another. As result of the melt blown, non-woven fiber structure in accordance to the invention whereby at least one filtration zone is comprised of relatively larger diameter support fibers integrally co-located with relatively smaller diameter filtration fibers, a filter cartridge having a wide range of "engineered" physical properties (e.g. in terms of filtration, pressure drop tolerance and the like) can be provided.

Title: Strain monitoring system
Inventor: EVERTSON DALE W
IPC: G01B13/24
Filed: 1996-10-21
Abstract: An apparatus (10) is provided for detecting deformation in solids in deep holes having a resilient vessel (12) pre-stressed into a rock formation. The vessel (12) is filled with fluid (14) and is sealed except for an outlet tube (16) of small diameter which extends all the way to, or close to, the surface (18). There the outlet tube (16) terminates in an extensible bellows (20). The whole apparatus is completely filled with fluid (14). Any deformation of the vessel (12) will cause fluid to be forced through the outlet tube (16) and so cause the bellows (20) to extend or contract. This motion can be monitored by any position-sensitive transducer (22) such as a linear variable differential transformer or capacitance bridge. A second tube (24) of the same length and size as the outlet tube (16) is filled with the same fluid. This tube (24) terminates at the bottom in close proximity to the resilient vessel (12). It also has a bellows (26) and a displacement transducer (28) at its upper end at the surface (18).

Title: Image processing apparatus
Inventor: HASLAM JANE
IPC: G06T1/00
Filed: 1998-08-04
Abstract: In  an  apparatus  and  method  for  creating  a three-dimensional model of an object, images of the object taken from different, unknown positions are processed to identify the points in the images which correspond to the same point on the actual object  (that is  "matching" points), the matching points are used to determine the relative positions from which the images were taken, and the matching points and calculated positions are used to calculate   points   in   a   three-dimensional   space representing points on the object.  A number of different techniques are used to identify the matching points, and a number of solutions are calculated and tested for the relative positions, the solution which is consistent with the largest number of matching points being selected.          In  one  matching  technique,  edges  in  an  image  are identified by first identifying corner points in the image and then identifying edges between the corner points on the basis of edge orientation values of pixels, the edges are processed in strength order to remove cross-overs,  the  images  sub-divided into  regions  by connecting points at the ends of the edges on the basis of the  edge  strengths,  and  matching  points  within corresponding  regions  in  two  or  more  images  are identified.

Title: A filter arrangement having at least two successive layers having predetermined spacing and its method for making
Inventor: CHOI KYUNG-JU
IPC: B01D39/06
Filed: 1998-09-29
Abstract: A filter apparatus and filtering method are provided herein. The filter media arrangement includes at least two successive layers of filter medium, each of the layers of filter medium being of preselected different and successively decreasing average pore size in upstream-downstream direct, in-line through-flow with the peripheral edges therefore in confined alignment in a flow channel for removing particulate matter from a fluid stream (e.g. an air stream) to be treated in said flow channel and/or confined chamber means disposed between the successive layers of filter medium to create a preselected, extensive, direct, in-line through-flow confined open space which is substantially free of interfering material extending parallel to, and within confined boundaries corresponding to peripheral edges of the contained aligned filter layer and between layers of adjacent spaced filter medium faces without any other substantial confinement. This thereby allows a fractionated, free-flowing, distribution of particles between the filter medium layers to maximize particulate holding capacity of the combined overall filter media. The filter media confined size arrangement including the layers of filter medium and the confined chamber member disposed therein is determined by the relative thickness and the mean flow pore size of the filter medium of each layer of filter medium and the average particle size in the treated air stream.

Title: Telephone communications network with enhanced signaling and call routing
Inventor: WHITTAKER RICHARD JONATHAN
IPC: H04M3/428
Filed: 1998-09-14
Abstract: Enhanced signaling and call routing is provided in a telephone communications network that includes a local telephone central office having a POTS line connection between a subscriber station and an access junction of the office. A voice path interfaces the access junction with a circuit switch for conventional dial-up voice call placement. Modem data calls, however, follow an access path from the junction as a physical switched connection terminated in layer 1 of a network data-switching matrix. The access path continues therefrom to a data switch which interfaces an Internet service provider. Interfacing the data and circuit switches, a network controller functions to selectively configure communications paths within the central office and between the office and network in response to commands originating at the subscriber station or incoming from other networks. Additional controller functions include blocking subscriber-originated traffic from the access path and queuing incoming network-side traffic when an Internet call is on hold, invoking a tear-down of the physical switched connection to free the access path for incoming and outgoing call attempts, converting PSTN-based voice signals to an IP-based voice format and transmitting any queued data to the subscriber station followed by restoration of normal data communications.

Title: Method and system for reducing interbeam interference and multipath fading in bent-pipe satellite communications systems
Inventor: SHERMAN MATTHEW J
IPC: H04B1/10
Filed: 1998-10-13
Abstract: A method and system of forming and processing communication links in a satellitecommunications system. The satellite communications system includes a plurality of groups of transmitters, a satellite and a plurality of destination receivers. Each transmitter is associated with only one transmitter group and transmits a communications signal. Each respective communications signal is a CDMA signal having a predetermined code that is associated with a transmitter. Each respective predetermined code is selected from a code set assigned to the group of transmitters with which the transmitter is grouped. Each code set is different from code sets associated with the transmitters of other selected transmitter groups so that the code sets are arranged in a code set pattern that is repeated for selected groups of transmitters. The satellite receives the communications signals and groups together each received communications signal having a same predetermined code set. The code sets of selected uplink communications signals in a group of received communications signals are fully or partially despread, filtered, and respread so that the group of communications signals contains communications signals from only one code set. Each group of communications signals is then transmitted to a different destination receiver, or groups on different code sets to the same destination receiver.
